Lithium slag-based anti-blocking ecological water permeable brick and preparation method thereof
The invention relates to a lithium slag-based ecological anti-blocking water permeable brick. The water permeable brick is of a double-layer structure formed by cementing a base layer and a surface layer, the base layer is prepared from the following raw materials in parts by weight: 20 to 25 parts of lithium slag ecological cement, 75 to 80 parts of 5 to 10 mm limestone gravel, 0.2 to 0.4 part of silica fume, 0.008 to 0.01 part of a water reducing agent and 7.2 to 10 parts of water; the surface layer is prepared from the following materials in parts by weight: 15 to 20 parts of lithium slag ecological cement, 80 to 85 parts of dried sand, 0.45 to 1.2 parts of water-borne epoxy resin, 0.1125 to 0.6 part of curing agent resin, 3 to 4.8 parts of water and 0.006 to 0.008 part of water reducing agent. The invention also provides a method for preparing the water permeable brick. The problem that a large amount of lithium slag is accumulated in the prior art can be solved, and when the lithium slag ecological cement is used for preparing water permeable bricks, the problems that the cost of the water permeable bricks is too high and the water permeable bricks are prone to saltpetering due to the too high mixing amount of the alkaline excitant can be solved.
本发明涉及一种锂渣基生态防堵塞透水砖，该透水砖是由基层和面层胶结形成的双层结构；所述的基层按重量份计由以下原料制成：20~25份的锂渣生态水泥、75~80份的5~10mm石灰岩类碎石、0.2~0.4份的硅灰、0.008~0.01份的减水剂、7.2~10份的水；所述的面层按重量份计由以下材料制成：15~20份锂渣生态水泥、80~85份的烘干沙、0.45~1.2份的水性环氧树脂、0.1125~0.6份的固化剂树脂、3~4.8份的水和0.006~0.008份的减水剂。本发明还提供制备所述透水砖的方法。本发明不仅可以解决现有锂渣大量堆积的问题，而且在利用锂渣生态水泥制备透水砖时，能够解决碱性激发剂掺量过高造成的透水砖成本过高及其容易泛碱的问题。
